Answer:
40 $1 bills. 30 $5 bills. 15 $10 bills. 4 $20 bills.
Step-by-step explanation:
In order to find how many there are of each in total, use the multiplication, division, subtraction, and addition property of equality.
For example, take the first equation. 1/2x +7=27
Follow these steps using the equalities
1/2x+7-7=27-7 Subtraction property of equality
1/2x·2=20·2 Multiplication property of equality
x=40
Do the other properties to find all the other equations. Here's the steps you should follow
5=1x-25
5+25=1x-25+25 Addition property of equality
5=x
3x+9=54
3x+9-9=54-9 Subtraction property of equality
3x/3=45/3 Division Property of equality
x=15
16=5x-4
16+4=5x-4+4 Addition Property of Equality
20/5=5x/5 Division Property of Equality
4=x
